RELEASE SAVEPOINT

Name

RELEASE SAVEPOINT -- destroy a previously defined
savepoint

Synopsis

RELEASE [ SAVEPOINT ] savepoint_name

Description

RELEASE SAVEPOINT destroys a savepoint
previously defined in the current transaction.

Destroying a savepoint makes it unavailable as a rollback point,
but it has no other user visible behavior. It does not undo the
effects of commands executed after the savepoint was established.
(To do that, see ROLLBACK TO
SAVEPOINT.) Destroying a savepoint when it is no longer needed
allows the system to reclaim some resources earlier than
transaction end.

RELEASE SAVEPOINT also destroys all
savepoints that were established after the named savepoint was
established.

Parameters

savepoint_name

The name of the savepoint to destroy.

Notes

Specifying a savepoint name that was not previously defined is
an error.

It is not possible to release a savepoint when the transaction
is in an aborted state.

If multiple savepoints have the same name, only the one that was
most recently defined is released.
